Product Description:

The MAC90C-0-KD-4-C/110-A-0/WI522/S001 is a member of the MAC AC Servo Motors series produced by Bosch Rexroth Indramat. Designed as a motor for analog drives, it converts electrical commands from legacy controllers into precise mechanical rotation for machine tools, printing lines, and assembly stations. A standard incremental encoder is mounted on the motor to return position feedback, allowing the drive to regulate speed and alignment in real time. This closed-loop arrangement supports controlled motion when the connected machine experiences changing loads or operating conditions.

While energized at rest, the rotor can produce a standstill torque of 10.4 Nm while drawing a standstill current of 17.0 A, allowing the machine to hold a load without a mechanical brake. During continuous motion, the motor operates at a nominal speed of 2000 rpm. The torque constant is 0.68 Nm/A, indicating the proportional relationship between winding current and generated torque. Typical operating cycles use a motor phase current of 13.9 A. The 60-minute thermal time constant indicates that the winding temperature changes gradually, allowing moderate short-term overloads while the motor remains within its insulation limits. These electrical characteristics help the connected analog amplifier regulate torque during acceleration, steady motion, and controlled stops.

Short bursts are supported by a peak pulse current of 125 A, allowing the shaft to accelerate loads with minimal delay. The winding has an inductance of 3.6 mH and a resistance of 0.60 ohm, which affect current rise time and copper losses in the analog drive stage. The rotor inertia is 53 × 10⁻⁴ kg·m², while the complete motor has a mass of 23 kg, balancing responsive acceleration with mechanical stability. The housing uses a centering diameter of 110 mm to support accurate flange alignment during installation. The incremental encoder delivers 2,500 pulses and operates from a 5 V supply through a standard mounting interface. Its feedback signal allows the drive to monitor shaft movement and correct deviations during positioning and speed-controlled operation.
